Mercedes-Benz E53 vs BMW IX1

What's the difference?

The Mercedes-AMG E53 Hybrid 4Matic+ is a superb blend of high-tech hybrid muscle and cossetting top-end luxury. Value is competitive, it looks (and feels) the business, despite the conventional sedan configuration it’s surprisingly practical (except for the modest boot), fuel-efficiency is a key benefit and safety is stellar. The ownership proposition is okay for the category but that’s not top of mind when an enticing series of corners ranges into view. It’s an impressive package.

BMW is a true EV pioneer, as the 2014 i3 and subsequent models prove. There’s never been one that we didn’t like. The only problem was that all were expensive. And at times, prohibitively so.

Astoundingly, the iX1 breaks that cycle, comparatively speaking, while impressing us with its design, quality, packaging, dynamics and equipment levels.

As it stands, the xDrive30 is one of the most convincing and best-value medium-sized luxury SUV EVs on the market right now.

Who’d have thought it from a BMW?

At first glance the E53 passes as a flash-looking Mercedes-Benz E-Class running 20-inch rims, especially in the launch car’s rich ‘Patagonia Red’ finish.

But then, there’s something about the AMG sedan’s stance that sets it apart. Which makes sense because the front fenders are wider by 11mm on both sides (compared to the E-Class) to make room for a wider front track (increased by just over 30mm over the previous-generation E53).

Wheelbase has also increased by just over 20mm to almost 3.0m and the car’s more aggressive nose treatment enhances the distinctive look.

There’s the AMG-specific radiator trim with ‘Panamericana’-style vertical slats, the sleek dual-section headlights and a large lower inlet that directs air to an additional front intercooler as well as an external opening for a wheel-arch cooler.

In profile there’s barely a hard edge to be seen, although character lines in the bonnet and along the car’s flanks contribute to a taut surface treatment.

At the rear, horizontally-connected LED tail-lights feature a stylised Mercedes three-pointed star signature, then a rear apron housing a diffuser and twin double tailpipe ‘trims’ and a bootlid spoiler on the left and right round off a beautifully proportioned design.

Climbing inside means a trip to screen city with an upright digital display in front of the driver flanked by a large central screen to the left and an additional panel for the front passenger beyond that. It’s a lot.

But once you’re on top of all the glass surfaces, details like open pore grey ashwood trim on the lower console come into focus, as do the brushed metal accents, beautifully sculpted ‘Performance’ front sports seats (optionally fitted to our launch drive example), racy stainless steel pedal covers and the five spoke AMG performance steering wheel with configurable rotary buttons.

It’s a supremely luxurious and comfortable interior. 

Arguably the prettiest new BMW SUV you can buy today, the well-proportioned iX1 is nearly impossible to spot over its almost-identical ICE (U11) X1 siblings.

Besides the badging, look for some blue trim bits and pieces inside and out, along with additional digital touchpoints inside.

And while both ride on the same all-new platform that’s resulted in a substantially larger body compared to previous X1 generations, the EV version seems a bit more slammed.

Dimensionally, the iX1 mirrors today’s X1 at 4500mm long and 1845mm wide, and still sits on the same 2692mm wheelbase, but is 26mm shorter at 1616mm tall and offers 35mm less ground clearance at 170mm.

Result? These plus a bunch of aero enhancements mean the slipperiest iX1 manages a Cd of just 0.26, according to BMW.

And, inevitably, the extra size equals more space inside.

At over 4.9m long, close to 2.1m wide and a little under 1.5m tall, with a 2961mm wheelbase, the new E53 is a substantial car and feels it on the inside.

Plenty of breathing space for the driver and front passenger thanks in part to the away slope of the screen-dominated dash.

Generous storage, too, with large door bins including enough space for big bottles, a deep lidded box between the seats (which doubles as a centre armrest), a generous glove box and two cupholders under a sliding top at the front of the centre console. 

Hit the second row, and sitting behind the driver’s seat, set for my 183cm position, I have plenty of head and legroom, with enough shoulder space for three adults on short journeys. A trio of up to mid-teenage kids will be fine for a road trip.

Storage is pretty handy as well with hefty door bins and two pop-out cupholders in the fold-down centre armrest. No map pockets on the back of the (optional) Performance front seats, though.

Four-zone climate control means there’s individual temperature control for each side of the back seat, with adjustable vents at the back of the front centre console and trailing edge of the B-pillars. Very civilised.

Power and connectivity runs to three USB-C outlets and a wireless device charging pad in the front.

Thanks to the traction battery under its floor, boot volume is restricted to 370 litres (compared to 540L in the conventional E-Class sedan), although there are bag hooks, tie-down anchors and the 60/40 split-folding rear seat is able to liberate more space.

No spare tyre of any description, just a repair/inflator kit, which might make sense for automotive designers and engineers trying to maximise space and reduce weight, but doesn’t make sense for an owner stranded on the side of the road with an unrepairable puncture.

BMW also says the iX1’s cabin is almost as roomy in some ways as the larger X3.

Large doors allow for easy entry and egress, onto sumptuous front seats that provide exceptional comfort and support even on longer journeys.

Surrounded by an expansive feeling of space, the interior feels light and airy, as well as fresh, inviting and premium looking – something previous-gen X1s were rarely accused of being.

We’re talking on-brand stuff here, beginning with the excellent driving position, ahead of a crisp and attractive dash that’s pleasing to behold. Push-button starting and a small toggle lever operates the transmission.

An ever-so-slightly curved (towards the driver in the best-BMW old-school way) rectangular binnacle houses two digital displays – a 10.25-inch one ahead of the driver offering an array of configurable electronic dials, as well as a 10.7-inch multimedia touchscreen.

BMW pioneered the multimedia controller more than 20 years ago with iDrive, and this descendent of that system reveals all that expertise gained by being intuitive to operate and quick to respond to commands once familiarised. Which shouldn’t take too long.

It’s all very-EV centric, as the industry inexorably moves to total electrification, but there were a couple of voice-command errors in the iX1, revealing that such systems are still far from perfect. BMW does provide audio volume and climate hard buttons, thankfully, so the basics are looked after.

Speaking of which, the iX1 offers decent levels of vision out, superb ventilation and ample storage in the doors, on the dash and between the front seats. And, as we’ve noted previously in BMWs, the upright smartphone charger is a clever idea. Keeps it in position and is handy to glance at.

Out back, backrest comfort and support is A-OK, and even with the optional sunroof, our test iX1 provided sufficient space for taller bodies, while expected items like ventilation grilles, USB ports and cupholders are fitted.

Note that, though the 40/20/40-split backrests recline slightly, they do not slide as per in the ICE X1, as this is a desirable option.

Nor is the cargo capacity as good in the iX1, due to the inevitable space demanded by that rear-axle-mounted electric motor and battery pack. For the record, ranges from 490 litres to 1495L instead of 540-1527L. Plus, there’s no spare tyre, with just a tyre repair kit fitted.

These aside, the iX1’s spacious and inviting interior remains one of the compact SUV segment’s best.

For now, only a single iX1 grade is available, dubbed xDrive30, starting from $84,900 (all prices are before on-road costs).

Most buyers seem to be choosing the no-cost-extra racier 'M Sport' pack over the more-conservatively presented 'xLine'.

Both come complete with double-the-usual AC charging capability (22kW), twin-motor all-wheel drive, a 67kWh battery, variable-ratio steering and adaptive dampers as standard.

In contrast, the Mercedes EQB 350 4Matic equivalent starts from over $107,000 (though a less-expensive single-motor front-drive version comes in from nearly $89,000), and both with a slower 11kW charger. Genesis’ advanced GV60, meanwhile, kicks off from nearly $108K.

We cannot remember BMW ever going so hard on comparative value in Australia, though how it responds to the sensational (though admittedly smaller) Volvo EX30’s $59,990 ask remains to be seen.

Anyway, the iX1 is no bare-bones special.

Besides the aforementioned twin electric motors, AWD, 22kW AC charger and (non-driver-configurable) adaptive dampers, there are goodies like keyless entry/start, a digital key with ultra-wide-band tech, a 10.7-inch multimedia touchscreen, a digital instrumentation cluster, ‘Hey, BMW!’ voice control, a head-up display, sat-nav with augmented reality view, dual-zone climate control, ‘Veganza’ artificial leather, a reversing camera, digital radio, Apple CarPlay/Android Auto connectivity, wireless phone charging, a powered tailgate, roof rails and 19-inch alloy wheels.

On the safety front, you’ll find driver-assist tech like autonomous emergency braking (AEB), lane-support systems, adaptive cruise control, adaptive LED headlights and automatic parking assist. More on those in the safety section below.

Need more but want to think less? BMW’s new and simplified option packs bundles key features like a panoramic sunroof, metallic paint (normally $1500 on its own), Harman Kardon audio upgrade, lumbar massaging front seats and alternative interior trims in a reasonably-priced $4700 'Enhancement Pack'.

There are several others bundles available, too, as well as a handy 22kW BMW AC Wallbox from $1199, not including installation, that cuts down home-charging from over 33 hours using the regular mains to around 3.5 hours.

And don’t worry, BMW diehards. You can still spend tens of thousands of dollars more via the company’s endlessly extensive options list. The Germans aren’t foolish.

Unlike in the iX3’s Hyundai, Kia or Genesis rivals, which use a pure EV skateboard platform and offer no internal combustion engine (ICE) alternatives on this architecture, there is no V2L Vehicle-to-Load capability. In other words, you cannot charge appliances or power your home in an electrical blackout scenario.

The E53 is powered by a 3.0-litre, turbo-petrol, in-line six-cylinder engine working in concert with an electric motor housed within the car’s nine-speed (torque-converter) automatic transmission. 

Drive goes to all four wheels via an electro-mechanically controlled clutch distributing power between the front and rear axles.

Engine performance is up by around 10kW compared to the previous E53 thanks to software upgrades, a new twin-scroll turbo with higher boost pressure (1.5 bar vs 1.1 bar) as well as additional front and wheel-arch intercoolers. 

The engine alone produces 330kW/560Nm while the permanently excited synchronous motor chips in with a solid 120kW/480Nm for overall outputs of 450kW/750Nm.

The iX1 boasts BMW’s fifth-generation EV drive system, known as eDrive 5.0 (M170SF).

Being an xDrive30, there are two electric motors fitted – one on each axle to provide all-wheel drive. Both are electrically excited synchronous motor set-ups.

Drive is predominantly to the front wheels via a single-speed reduction gear transmission, unless extra traction is required, in which case the rear motor kicks in to power the back axle.

Combined with the aid of an overboost function, they deliver 230kW of power and 494Nm of torque, for a 0-100km/h sprint time of 5.6 seconds, on the way to a 180km/h top speed.

Tipping the scales at 2010kg, the xDrive30 provides a power-to-weight ratio of 114kW per tonne, which is a healthy number.

Suspension is via MacPherson-style struts up front and an independent three-link design out back.

If you care, towing limits are 1200kg braked and 750kg unbraked, with a 570kg maximum payload.

The E53’s official combined cycle (urban/extra-urban) fuel figure is 1.7L/100km, a spectacularly frugal number for such a high-performance machine. But it’s worth noting it’s predicated on the drive battery being constantly and completely recharged.

Speaking of which, the 28.6kWh, 400-volt traction battery is housed at the rear of the car under the boot floor. It delivers a claimed EV-only range of up to 100km, although that will diminish dramatically if you decide to push up towards the car’s pure-electric top speed of 140km/h.

Important to note the battery’s 21kWh ‘day-to-day’ capacity, designed to keep charge in reserve for any required ‘high-performance boosts’.

An 11kW AC charger is onboard with regenerative braking also harvesting energy, the car automatically selecting the level of recuperation power in line with traffic conditions.

In pure EV mode you can also manually adjust regen through four levels via the steering wheel-mounted transmission shift paddles. 

Auto stop/start for the engine is standard and 98 RON premium unleaded is recommended, although 95 RON is okay at a pinch.

The E53’s official fuel consumption figure and 50-litre tank capacity translate to a range approaching 3000km! But to bring that down to earth somewhat, on the launch drive program, covering urban and mostly highway running, we saw a (dash indicated) average of 6.4L/100km, which equates to a more realistic, but still lengthy, 780km between fills.

BMW says the xDrive30 consumes an average of 18.3kWh/100km.

On the launch drive program, the vehicle displayed 21.3kWh/100km. That included some spirited highway and mountain-road driving conditions.

Fitted with a 67kWh lithium-ion battery pack with a useable 65kWh, the iX1 offers an ADR 81/02-rated range of 400km.

This means a relatively common 50kW DC public charger with a CCS Combo 2 socket will need about 65 minutes to replenish the battery from 10 to 80 per cent or about half an hour with a 150kW charger.

If neither are available, you'll require about 34 hours to charge to 100 per cent maximum using the normal household powerpoint plug. Or, as mentioned earlier, a 22kW AC Wallbox cuts that down to about 3.5 hours.

Each iX1 includes a three-year subscription with Chargefox.

If you’re lining up for a Mercedes-AMG you want an optimal blend of luxury and performance and the E53 Hybrid 4Matic+ nails that delicate balance.

With 450kW (that’s 612hp!) and 750Nm under your right foot, engaging ‘Race Start’, pushing the accelerator to the floor and letting the car do its thing will result in 0-100km/h acceleration in 3.8 seconds. The fat band of mid-range torque is so satisfying to lean into.

Induction, engine and exhaust sounds combine to produce a suitably gruff soundtrack with the hybrid powertrain operating seamlessly. Hit your preferred track day or tempt legal fate and you can explore the car’s claimed (governed) maximum velocity of 280km/h. 

The nine-speed auto is slick and manual changes using the wheel mounted paddles are rapid.  In normal conditions the AWD system is biased to the rear and an electric rear locking diff helps keep things under control if you decide to get the bit between your teeth on a twisting drive.

A chunky brace links the front suspension strut mounts and the car feels predictable and stable in enthusiastic cornering. Rubber is Michelin Pilot Sport 4S (245/35 fr / 275/30 rr) which grips with satisfying determination but does make its rumbling presence felt on anything approaching a coarse chip surface (despite the car’s standard acoustic glass).

Speed-sensitive power-steering delivers accuracy and good road feel without any jitters, the standard active rear-axle steering playing its part. The ‘turning point’ is 100km/h with the rear wheels subtly turning in the opposite direction to the fronts up to that speed and in the same direction beyond it.

‘AMG Ride Control’ combines steel spring suspension (strut front, multi-link rear) with adaptive adjustable damping for the choice of ‘Comfort’, ‘Sport’ and ‘Sport+’ settings. Comfort is the pick for B-road running on typically uneven surfaces. The optional ‘Performance’ sports front seats are comfortable and grippy in equal measure. 

Braking is by ventilated composite rotors all around, with beefy four-piston fixed calipers up front. An electro-mechanical brake booster is designed to combine electrical recuperation with the hydraulic brake for more frequent and efficient energy harvesting over a longer period of time. The pedal feels firm and progressive with smooth initial bite. 

All around vision is good for a conventional sedan with a quality reversing camera, 360-degree overhead view and front and rear parking sensors helping massively with parking duties. That said, a 12.5m turning circle isn’t tiny.

One of the best things about the iX1 xDrive30 is that it has just enough EV smoothness, refinement and speed to feel special, yet still drives and behaves as a BMW should.

Which hasn't always been the case with previous-gen X1s.

It helps that, from the driver’s seat, everything falls into place: the bracing seats, thoughtfully positioned relative to all controls; and the overall sporty/quality ambience that puts you into the brand mindset.

Select Drive, and the iX1 leaps away sweetly and silently, accompanied by an electric motor whir that's quite pleasing. At speed, acceleration is instant for fast overtaking and there’s plenty more in reserve if you really need to hustle along.

For a 2.0-tonne compact SUV, the steering is remarkably responsive, providing nimble yet secure handling. Maybe it’s all the low-slung weight and near-50:50 weight distribution, but the iX1 displays impressive cornering and road grip. It’s an enjoyable drive.

Initially, novices might find the brakes a bit sudden, but they’re actually pretty progressive once you get used to them, and they feel and stop with a more natural pedal feel than many hybrids we’ve experienced. Again, BMW has tuned the xDrive30 to feel inclusive.   

Speaking of the stoppers, there are no paddle shifters to control the amount of single-pedal off-accelerator braking as per many other EVs, but putting the transmission from ‘D’ to ‘B’ brings a decent level of deceleration if not a full stop – as if you’re lighting resting your foot on the pedal. We’d like the option of a heavier self-braking function, though.

The launch program avoided city roads and heavy traffic, but we still found plenty of bad, pot-holed surfaces to favourably judge the adaptive dampers’ ability to help soak up the bumps.

While not super-soft or supple, the suspension is cushy enough for a comfy ride. And certainly better than many past BMW SUVs.

A bit too much road and tyre noise intrusion aside, the xDrive30 is dynamically very sorted indeed.

Which, when you consider all the other positive aspects of the iX1, you end up with a BMW offering an impressively broad band of capabilities.

It’s rapid, nimble and reactive to driver inputs, as you’d expect an SUV from this brand to be, without the compromise of harshness or discomfort.

What it’s like around town in a peak-hour crawl, or how far you can really get from a fully-charged battery, is something we’ll find out when we can conduct a full road test, so please watch this space.

Until then, as it stands, things are looking promising indeed for the xDrive30. Especially factoring in the value pricing.

ANCAP awarded the X1 petrol versions a five-star rating in 2022, based on the European NCAP result. No separate iX1 figure is as-yet available.

The iX1 comes with many of the latest driver-assist safety tech features, including AEB with day/night pedestrian and cyclist detection. This system is operational from 5.0km/h.

You'll also find front and rear cross-traffic alert, secondary collision avoidance braking, as well as a blind-spot monitor, lane-departure warning and swerve-assist systems, speed assist tech like adaptive cruise control with full-stop/go functionality, stability and traction controls, anti-lock brakes with brake-assist and a drowsy driver alert.

The lane support systems start from 60km/h and the driver monitoring system kicks in from 70km/h.

Along with dual-front airbags, the front-seat occupants have side chest and side pelvis airbag protection, as well as an airbag between them to help mitigate lateral-impact injuries while outboard rear-seat occupants have side head airbags (also called curtain airbags) coverage. The total airbag count is seven.

ISOFIX child-seat latches are fitted to outboard rear seat positions, while a trio of top tethers for straps are included across the back bench.

The Mercedes-AMG E53 Hybrid 4Matic+ is covered by a five-year/unlimited km warranty with the high-voltage battery covered for eight years/160,000km. Those terms match the key players in the premium and luxury parts of the market.

Mercedes-Benz ‘Road Care’ assistance is included for the duration of the main vehicle warranty. 

Maintenance is recommended every 12 months/25,000km, with service plans offered across three- ($4110), four- ($5410) and five-year ($7570) periods. That’s an average of around $1350 for the first two and $1500 for the last one. That added powertrain complexity obviously has an impact in the workshop.

Last year, BMW introduced a five-year/unlimited kilometre warranty with all its products, finally catching up with the industry warranty average after a protracted period of just a three-year coverage.

While there’s no capped-price servicing, you can pre-purchase a number of service bundles, to help save a bit more money further down the track.

There's a choice of 'Basic' or 'Plus' packages, in four or six-year (both with unlimited kilometre) programs, known as 'Service Inclusive'. They cost $1263/$4784 and $1800/$5784, respectively. 'Plus' covers brake pads/discs and wiper blade rubbers.

Note, however, that roadside assistance remains at three years.

Keep in mind, too, that BMW vehicles have a self-diagnosis feature that varies the service intervals according to how they’re used as well as wear and tear.

Our advice is to keep making an appointment annually or at about every 10,000km, just to be on the safe side.
